class Employee(object): """Models real-life employees!""" def __init__(self, employee_name): self.employee_name = employee_name def calculate_wage(self, hours): self.hours = hours return hours * 20.00 # Add your code below! class PartTimeEmployee(Employee): def calculate_wage(self,hours): self.hours = hours return hours * 12.00 def full_time_wage(self,hours): return super(PartTimeEmployee,self).calculate_wage(hours) milton = PartTimeEmployee("Howe") print milton.full_time_wage(10)
So when I called super() I need to simplify the argument which is PartTimeEmployee and it called the its father Employee and send the argument self, so I can use the calculate_wage to print the result.
In fact in Python 3.0, the super() is much more clearer to use, just super().calculate_wage(hours) is okay to be used.
